Abstract

A display apparatus includes: a signal receiving unit which receives an image signal from an imaging device; an image processor which performs an image processing operation on the image signal received by the signal receiving unit; a display unit which displays an image based on the image signal processed by the image processor; and a controller which determines characteristics of the imaging device, and controls the image processor to perform a color compensation on the displayed image according to the characteristics of the imaging device.

1 . A display apparatus comprising:
 a signal receiving unit which receives an image signal from an imaging device;   an image processor which performs an image processing operation on the image signal received by the signal receiving unit;   a display unit which displays an image based on the image signal on which the image processing operation has been performed; and   a controller which determines characteristics of the imaging device, and controls the image processor to perform a color compensation on the displayed image according to the characteristics of the imaging device.   
   
   
       2 . The display apparatus of  claim 1 , wherein the imaging device comprises a video adapter which generates the image signal, and the controller controls the color compensation to be performed if the video adapter is replaced with another video adapter. 
   
   
       3 . The display apparatus of  claim 2 , further comprising a data storage unit which stores a first identification information of the video adapter,
 wherein the signal receiving unit further receives a second identification information of the video adapter from the imaging device, and the controller determines whether the video adapter is replaced with another video adapter by comparing the first identification information with the second identification information.   
   
   
       4 . The display apparatus of  claim 3 , wherein the first and second identification information include a driver information of the video adapter. 
   
   
       5 . The display apparatus of  claim 3 , wherein the controller determines whether the video adapter is replaced if a connection with the imaging device is established. 
   
   
       6 . The display apparatus of  claim 5 , wherein the controller updates the first identification information with the second identification information of the corresponding video adapter and stores the updated first identification information after performing the color compensation. 
   
   
       7 . The display apparatus of  claim 1 , wherein the color compensation includes a compensation of RGB levels of the displayed image based on a white level of the received image signal. 
   
   
       8 . The display apparatus of  claim 7 , wherein the controller controls the image processor not to perform the color compensation if a white pixel of the image of the received image signal does not continue for a time period. 
   
   
       9 . The display apparatus of  claim 8 , wherein the controller displays a message on the display unit so as to request execution of an application program from a user if the white pixel of the image of the received image signal does not continue for the time period. 
   
   
       10 . The display apparatus of  claim 8 , wherein the controller requests to execute an application program from the imaging device if the white pixel of the image of the image signal does not continue for the time period. 
   
   
       11 . A control method of a display apparatus which displays an image based on an image signal received from an imaging device, the control method comprising:
 determining characteristics of the imaging device; and   performing a color compensation of the displayed image according to the determined characteristics of the imaging device.   
   
   
       12 . The control method of  claim 11 , wherein the imaging device comprises a video adapter which generates the image signal,
 the determining the characteristics of the imaging device comprises determining whether the video adapter is replaced with another video adapter, and   the performing the color compensation comprises performing color compensation of the displayed image if the video adapter is replaced.   
   
   
       13 . The control method of  claim 12 , further comprising:
 storing a first identification information of the video adapter;   receiving a second identification information of the video adapter from the imaging device,   wherein the determining whether the video adapter is replaced comprises comparing the stored first identification information with the second identification information.   
   
   
       14 . The control method of  claim 13 , wherein the first identification information and the second identification information include a driver information of the video adapter. 
   
   
       15 . The control method of  claim 13 , wherein the determining whether the video adapter is replaced is performed if the imaging device is connected to the display apparatus. 
   
   
       16 . The control method of  claim 13 , wherein the storing of the first identification information comprises updating the first identification information of the corresponding video adapter with the second identification information and storing the updated first identification information after performing the color compensation. 
   
   
       17 . The control method of  claim 11 , wherein the color compensation comprises a compensation of RGB levels of the displayed image based on a white level of the received image signal. 
   
   
       18 . The control method of  claim 17 , further comprising determining whether a white pixel of the image of the received image signal is continued,
 wherein the color compensation is performed if the white pixel of the image of the received image signal is continued for a time period.   
   
   
       19 . The control method of  claim 18 , further comprising displaying a message for requesting execution of an application program from a user if the white pixel of the image of the received image signal is not continued for the time period. 
   
   
       20 . The control method of  claim 18 , further comprising requesting of an application program from the imaging device if the white pixel of the image of the received image signal does not continue for the time period. 
   
   
       21 . A display system comprising:
 an imaging device which generates an image signal; and   a display apparatus which determines characteristics of the imaging device, performs a color compensation on an image of the image signal received from the imaging device according to the characteristics of the imaging device, and displays the color-compensated image.   
   
   
       22 . The display system of  claim 21 , wherein the display apparatus requests an execution of an application program from the imaging device when a white pixel of the image of the received image signal does not continue for a time period, and the imaging device executes the application program upon the request of the display apparatus.
